Competency Area 8: Concentrated source pollution AEM

PO 80. Understand the various methods to manage and treat silage leachate.

Low volumes of highly concentrated leachate should be collected and diluted prior to land application.

This is commonly done by adding small amounts of leachate to dry manure prior to disposal with a spreader, or to transfer the low flow to the manure lagoon for later spreading. Silage leachate that has been diluted with storm water runoff can be either added to the manure storage lagoon, or when concentrations are acceptable, the wastewater can be diverted to appropriately-designed vegetated filter areas or perhaps be applied directly to crop fields.
